BACKGROUND AND SUMMARY OF THE INVENTION

This is a continuation-in-part application of U.S. application Ser. No. 07/975,603, filed Nov. 12, 1992, now U.S. Pat. No. 5,396,027 for a "Strip Electrical System."

The present invention relates to a surface mounted continuous wiring system. More particularly, the present invention relates to a modular wiring system for mounting on the surface of a wall or wall panel to supply electrical power to the wall or wall panel.

Modern offices often use free-standing partitions or wall panels to form individual office cubicles in an open office environment. These cubicles provide a proper working environment while maintaining versatility and mobility for unrestricted office organization and expansion. It is essential that each of the cubicles formed by the wall panels is provided with electrical power. Therefore, various wiring systems which permit adjacent panels to be electrically coupled together have been developed. Wall panels often need to be assembled, disassembled, or reconfigured to provide larger or smaller work stations. Therefore, it is essential that the wiring system be flexible and easy to reconfigure. It is known to provide various types of wiring harness assemblies located inside wall panels to supply power to the wall panels.

The present invention is designed to be mounted on an external, exposed surface of the wall panels or on an exposed surface of any existing wall in the building to provide electrical power to that area of the building. The present invention is designed to minimize the amount of copper required and to provide a continuous wiring system which is easy to install with no complex wiring to install.

Because the continuous wiring system of the present invention is mounted on an external exposed surface of the wall, the continuous wiring system of the present invention can be placed at any height on the wall for easy access. Therefore, the surface mount continuous wiring system of the present invention facilitates supplying electricity to any desired area of a building. Advantageously, the surface mount continuous wiring system of the present invention simplifies installation and is easy to reconfigure if desired.

According to one aspect of the present invention, a wiring assembly is provided for mounting on an exposed surface of a wall or wall panel to supply electrical power to the wall or wall panel.

Cover 256 is also configured to include gussets 316 that lie adjacent plate 263 when cover 256 is coupled to body 242. Gussets 316 provide strength reinforcement to cover 256 when a standard three-prong plug 320 (shown in FIGS. 11b and 11c) is inserted into apertures 258. As can be seen in FIG. 11a, a space 322 is defined between gussets 316 of cover 256. Plug 320 is inserted into apertures 258 within space 322 as shown in FIG. 11c.

A jumper 324 used to interconnect adjacent wiring assemblies 200 is shown in FIG. 12. Jumper 324 includes a body 326 configured to include a plurality of apertures 328 that receive a plurality of conductive clips 330. Bus bar conductive clips 330 are configured to include connectors 332 that couple selected ones of bus bars 228 of adjacent wiring assemblies 200 together. Jumper 324 couples to adjacent supports 210 so that third portions 342 of conductive bus bars 328 are positioned to lie between adjacent supports 210 and body 326 of jumper 324. Jumper 324 also includes a cover 334 that couples to body 326 via a pair of fasteners 336 that pass through apertures 338 of cover 334 and apertures 340 of body 326. A plate 335 is positioned to lie between conductive clips 330 and cover 334. Plate 335 helps keep clips 330 within apertures 328 as well as against body 326 so that engagement with bus bars 228 is maintained. Plate 335 also includes apertures 337 through which fasteners 336 pass. Fasteners 336 secure body 326, conductive clips 330, plate 335, and cover 334 together and couple jumper 324 to supports 210.

As can be seen in FIGS. 13a-13c, both body 326 and cover 334 of jumper 324 include the same structure as body 242 and cover 256 discussed above. Body 326 includes dividers 344, that define spaces 346 into which conductive bus bars 228 are positioned to lie when body 326 is coupled to support 210. First and second side members 348 and 350 of body 326 and adjacent dividers 344 define second spaces 352 into which sidewalls 218 and 220 are positioned to lie. Third spaces 354 are defined between adjacent dividers 344. First dividers 222 of support 210 are positioned to lie within third spaces 354 when body 326 is attached to support 210. Body 326 further includes strips 356 that extend into spaces 291 of second dividers 224 when body 326 is coupled to support 210. Finally, body 326 is configured to include a fastener stud 358 that receives fasteners 336 (only one of which is shown in FIG. 13a) when used in combination with butterfly nuts 360 (only one of which is shown in FIG. 13a) to couple jumper 324 to support 210 as discussed above in connection with the coupling of outlet 238 to support 210.

Cover 334 of jumper 324 includes gussets 362 for strength reinforcement of cover 334 as discussed above in connection with gussets 316. Cover 334 also includes side members 364 and 366 that are positioned to lie adjacent first and second side members 348 and 350 of body 326 when cover 334 is attached thereto.

The jumper of the present invention can be configured to electrically couple adjacent wiring assemblies mounted on the exposed surfaces of wall panels that are angled relative to one another, such as wall panels 14 and 16 shown in FIG. 1. FIG. 14a illustrates a jumper 370 for interconnecting adjacent wiring assemblies 200 mounted on the exterior exposed surfaces of wall panels that are angled approximately 90° relative to one another. Jumper 370 includes first and second body portions 372 and 374 that are positioned to lie adjacent one another so that the first ends of body portions 372 and 374 abut one another generally along a line 376. Apertures 378 and 380 receive fasteners 382 and 384 that couple jumper 370 to adjacent supports 210 of adjacent wiring assemblies 200 as described above.

An alternative embodiment of the jumper of the present invention for electrically coupling adjacent wiring assemblies 200 located on the interior of exposed surfaces of wall panels angled relative to one another at an angle of approximately 90°, such as wall panels 14 and 16 of FIG. 1, is shown in FIG. 14b. First and second body portions 386 and 388 of jumper 384 include first ends that are positioned to abut one another generally along line 390, as discussed above in connection with jumper 370 shown in FIG. 14a. First and second body portions are each configured to include apertures 392 and 394 that receive fasteners 396 to couple jumper 384 to adjacent supports 210 of adjacent wiring assemblies 200 as discussed above in connection with jumpers 324 and 370. Although not shown, it should be noted that other angles for the jumper of the present invention are possible. For example, first and second body portions of an alternative embodiment of the jumper of the present invention could be angled relative to one another at an angle of approximately 45°. This would allow wiring assemblies 200 located on either interior or exterior exposed surfaces of wall panels angled at generally 45° relative to one another to be interconnected.
